1. The problem statement, all variables and given/known data A 1200 kg car traveling at 13 m/s is able to skid to a stop over a distance of 30 meters. What must be the coefficient of friction between the road and the tires for this to be possible? m= 1200kg Vo= 13 m/s V= 0 m/s x= 30 m 2. Relevant equations I think this is kinetic friction so: fk=µkFn 3. The attempt at a solution I know I want to solve for µk but we haven't been over this in class and I am not really sure how to solve for it. I also don't know how I arrive at fk and Fn from the info I was given.
